The checks
Three quick checks, about a minute in total
Run them in order for a rough pass/fail. Every result appears in the summary below, ready to send if you want a repair.
DRIFT CHECK 2 of 3
Let go of both sticks and leave the controller still for 3 seconds. A healthy stick rests within 5% of center.

How steady is your controller at rest?
A 2-second gyro stillness screen, then a button press and a resting-center sample. Read-only: no settings, calibration or permanent saves are written to your controller.
AT-REST CHECK PS5 + XBOX
Connect just one controller and press a controller button so the browser can see it. Set it on a stable surface. PS5 gyro needs desktop Chrome or Edge and WebHID permission; USB is recommended. Xbox skips the gyro. Do not touch the sticks or use another calibrator during the test.
Ready. Without anonymous sharing selected, readings stay in this page only.
Privacy & what this comparison means
Only if you opt in, we save model, connection type, browser family (not its version), gyro noise in raw sensor units if available, left/right radial center offsets, and the server receipt time. No name, email, serial number, device ID, account, raw motion trace or IP address is collected or saved by this app. A random page-session key is hashed for rate-limit counters, never linked to or saved with results. Counters expire after at most two minutes; expired rows are cleared on the next API request. Cloudflare still processes network requests for hosting and security under its own policies.
Comparisons use previous same-model tests, not verified unique people. Lower offsets are better; ties split. Fewer than 30 prior tests are marked Early data. Browsers, operating-system deadzones, calibration, connection types and repeat submissions affect readings, so this is not a laboratory hardware ranking, a gyro calibration or an S-tier rating. A zero reading may just be a browser deadzone. Precise app testing is coming soon.

BROWSER CALIBRATORS THAT SAVE PERMANENTLY
- Can leave it worse off. If the sticks aren't centered, the controller is a clone, or the cable drops mid-write, the bad calibration is stored in the controller.
- Limited data. Browsers poll and round what the controller sends, so fine drift and jitter get smoothed away.
- No real undo. Close the tab and the old calibration is gone, with no backup across sessions.
- No verified result. You get a picture of a circle, not a measured pass/fail.

- Test-only calibration. Nothing is saved to the controller, and it resets when you turn it off.
- Rough pass/fail for drift, range, buttons and triggers.

FAQ
What's the difference between TMR and Hall-effect sticks?
Both read the stick with magnets instead of the carbon tracks that wear out and cause drift. TMR (tunnel magnetoresistance) is the newer of the two: more precise and lower power.
Will my controller still work with my console?
Yes. Same pairing, buttons and features. We only replace the sticks.
How does the drift trade-in work?
Bring your drift-only controller plus $25 and swap it for a drift-free controller of the same model, same day. No cracked shells or water damage.
What does the warranty cover?
1 year on stick upgrades and workmanship, tied to the serial number. It excludes drops, cracks, liquid damage, and controllers opened by others.
How does mail-in work?
Email or text us first. Turnaround is 2–4 days after it arrives, and the customer covers return shipping.
Is the free browser check accurate?
It's a rough pass/fail. Browsers round and smooth what the controller sends. Precise readings and the S-tier rating will be in the Stellar Lab desktop app (coming soon).
Does the free calibrator change my controller?
Not permanently. It's test-only: nothing is saved to the controller, and it resets when you turn it off.
